Halcyon’s Active Control Ballast (ACB) integrated weight system can hold up to 10lbs (4.4kg), which means that it can fit 5lb (2.2kg) on each side. The vertical orientation takes up little space and still allows you to mount a primary light on your harness system.

The two weight pockets are complementing the existing ballast option of the Halcyon systems, and they can help fine-tuning your buoyancy. They can be used with most common hard or soft weights. Halcyon’s ACB weight pockets have a side release buckle, which prevents the accidental loss your weights.

Sold as a pair only.
